COMBINED HEATER AND SPARK-CONMEYER FOR RAILROAD-CARS.

SPECIFICATIONormng part of Letters Patent No. 435,199, `dated August 26,18920. Application tiled March 15, 1.889. `Serial No. 303,470. (Nomodel.)

To all whom t may concern/c Be itknown that I, WILLIAM AMos, a citi-'Zenofv nieunited states, residing at Providence, in the State of RhodeIsland,have in-` vented a new and useful'lmprovement `in Combined Heaterand Spark-Conveyer for Railroad-Cars, of which the following is aspecification.

The great danger of iire and consequent loss of life in the case ofarailroad accident makes it desirable to provide a substitute for thecar-heating stoves heretofore employed; and it is also desirable to beable to prevent the sparks from flying into the cars through the opendoors or windows.

It is the object of my invention to furnish a practicable device, bymeans of which the sparks from the furnace of the locomotive can beconveyed to the `rear of the train, and the passenger-cars of` the traincan be properly heated from the exhaust-steam and the escaping productsof combustion from the locomotive.

My invention consists in the combination,

with the smoke-stack of the locomotive, of a jointed pipe extending tothe rear of the train over and through the top portion of the car andprovided with joints between the several cars to permit the requiredangular movement when turning around a curve in the track, and to allowfor the necessary vibration of one car with another, and a swingingValve for optionally directing the exhaust-steam and the products ofcombustion either through the said jointed pipe or through thesmoke-stack.

My invention also consists in the improved arrangement for regulatingthe heat in the car, and in a combination with loose guides, springs,and collars for supporting the pipesection, which passes through thecar, as hereinafter fully set forth.

Figure l represents an elevation of a locomotive and train of carsprovided with my improvement. Fig. 2 represents a detail view of theceiling of a railroad-car, showing the under. side of the box whichsurrounds the heating and conveying pipe. Fig.. 3 represents a detailside View of the box which surrounds the heating and conveying pipeunder the monitor-roof of the car, the said roof being shown in section.Fig. 4 is a detail transverse section ofthe upper part of acar,showinglateral discharge-pipes extending outward from the mainpipe.4 Fig. 5 is an enlarged elevation of the forward partof the,locomotive. Fig. 6 is an enlarged detail section showing the valve forchanging thedirection of the exhaust either through the heating pipe orthrough the smoke-stack. Figs. 7 4,and

8 are enlargeddetail views showing the guide 6o for loosely supportingthq, pipe-section which passes through the car.

In the accompanying drawings, A is the locomotive, B the tender, and O Cthe Vpassenger-cars of the train.

To the base of the smoke-stack D of ythe locomotive, and at an acuteangle with the same, is attached the heating andconveying pipe E, whichpasses rearward over the tender, thence over the main roof j of` thefirst car O, and 7o under the monitor-roof f `of the same, thus reachingthe interior of the car for heating purposes. The exhaust-steam and theproducts of combustion from the furnace of the locomotive-boiler can bemade to pass either directly into the atmosphere through the smoke-stackD, or rearward through the heating and conveying pipe E, by. means ofthe Valve F, which is shown in the enlarged section, Fig. 6, the saidvalve being formed of a 8o fiat plate attached to the rock-shaft a,which is located at the angle formed by the j unction of the pipe E withthe smoke-stack D, and to the outer end of which is secured the arm b.The shaft ct is connected to the handleverc in the cab of the locomotiveby means of the rod d, so that the engineer, by moving the hand-lever c,can direct the exhaust-steam and heated products of combustion, asdesired, either wholly through either the heat- 9o ing and conveyingpipe E or the smoke-stack D, or partially through both, in which lattercase the valve will be set at the intermediate point, as shown in Fig.6. The engineer can thus control the amount of exhaust-steam andproducts of combustion to be delivered to the pipe E for car-heatingpurposes; and

`in carrying out this part of my invention I prefer to carry thejet-pipe @for the exhauststeam nearer the base of the smoke-stack `D Ioothan has been common heretofore, as shown in Fig. 5, the exhaust-pipebeing represented by dotted lines, and the valve F is so arranged thatits lower edge can be swung from side to side over the opening in thejetpipe c at the will of the engineer, thus directing the jet of steamin either direction Without materially retarding its velocity. Thepipesection m extends under the monitor-roof f of the car, and isloosely held at its -ends by means of the annular guides g g, which fitaround the said pipe and are attached to the main roof j. At each sideof the fixed guide g and around the pipesection m is placed a spiralspring 7L, which is held between a collar t' and the said guide,-and bymeans of the said guides and the oppositely-arranged collars and springsproper allowance will be made for the expansion and contraction of thepipe m, and the said pipe will be properly held in position upon thecar.

The coupling-joint G, between the cars C C, is formed by means of theenlargements n upon the pipes m, which are provided with the flangedrings p for holding the coupling-pipes, the coupling-pipe m providedwith the enlargement n', andl the coupling pipe m adapted to enter theenlargement n of the pipe m, the said coupling-pipes being supportedfroii the roofyl of the car by means of the pipe-holding guides II.

The locomotive-tender B is provided with a Xed pipe m0, and the couplingG', between the tender B and the forward car G, is formed withacoupling-pipem", upon which is placed vthe' movable sleeve n, which,when moved forward and secured in position by suitable means, will serveto form a bell-shaped enlargement to receive the forward end of thecoupling-pipe m of the car C, the said coupling-joints G and G beingshown, described, and claimed in my Letters Patent of the United StatesNo. 420,220, to which reference is made for a fuller description of thesame.

The pipe m passes through the upper part of the car, immediately underthe monitorroof f, and is inclosed in a box I, the said box beingprovided at its under side with a series of registers c', which may beopened or closed at pleasure to supply the proper amount of heat to theinterior of the cai-,and other registeropenings c may be made upon thever-A laterally from the main conducting-pipe 'mj when not needed forthe purpose of heating the car.

1. The combination, with the locomotive smoke-stack and the jointedheating and conveying pipe extending rearward through the car and joinedto the smoke-stackat an acute angle, of the jet-pipe for theexhaust-steam, and the valve pivoted at the angle between thesmoke-stack and the heating and conveying pipe and adapted to have itslower edge swung from side to side over the dischargeorifice of thejet-pipe, substantially as described.

2. A railway-car provided with a heating and conveying pipe passingthrough the car and loosely held by the iiXed guides attached to thecar, and having the springs and the attached collars at opposite sidesof t-he iixed guides, substantially as described.
